Hlau 3D luam ntawv tshuab hmoovmolding txheej txheem cov ntsiab lus, cov ntaub ntawv kub, raws li qhov tseem ceeb tshaj plaws ntawm cov hlau qhov chaw 3D luam ntawv kev lag luam saw, kuj yog tus nqi loj tshaj. Nyob rau hauv lub ntiaj teb 3D luam ntawv kev lag luam lub rooj sib tham 2013, cov kws txawj nyob rau hauv lub ntiaj teb no 3D luam ntawv kev lag luam muab ib tug meej lub ntsiab lus ntawm 3d luam ntawv hlau hmoov, uas yog, qhov luaj li cas ntawm tsawg tshaj li 1 hli ntawm hlau hais. Nws suav nrog tib cov hmoov hlau, cov hmoov hlau alloy thiab qee cov tshuaj refractory compound hmoov nrog cov cuab yeej hlau. Tam sim no, 3D luam ntawv hlau hmoov cov ntaub ntawv muaj xws li cobalt-chromium alloy, stainless hlau, muaj hlau, tooj liab alloy, titanium alloy thiab nickel-aluminium alloy. Tab sis 3D luam ntawv hlau hmoov yuav tsum tsis yog tsuas yog muaj cov yas zoo, tab sis kuj ua tau raws li qhov yuav tsum tau muaj ntawm qhov loj me me, nqaim particle loj faib, siab sphericity, zoo fluidity thiab siab xoob ntom. Vim yog cov kev cai sib txawv ntawm daim ntawv thov thiab cov txheej txheem molding tom ntej, kev npaj cov hmoov hlau kuj txawv. Raws li cov txheej txheem kev npaj, nws feem ntau suav nrog txoj kev siv lub cev chemistry thiab kev siv tshuab. Hauv kev lag luam hmoov metallurgy, txoj kev xws li electrolysis, txo thiab atomization yog dav siv. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias ob txoj kev muaj lawv cov kev txwv, tsis haum rau kev npaj cov hmoov txhuas. Tam sim no, hlau hmoov rau additive manufacturing mas yog concentrated nyob rau hauv titanium alloy, kub kub alloy, cobalt-chromium alloy, siab zog steel thiab tuag hlau. Txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm cov khoom siv ntxiv thiab cov txheej txheem, cov hmoov hlau yuav tsum muaj cov yam ntxwv ntawm cov ntsiab lus qis ntawm cov pa oxygen thiab nitrogen, zoo kheej kheej degree, nqaim particle loj faib ntau yam thiab siab xoob ntom. Tam sim no, cov txheej txheem tseem ceeb ntawm kev npaj cov hmoov hlau rau kev tsim khoom ntxiv yog plasma rotating electrode (PREP), plasma atomization (PA), roj atomization (GA) thiab plasma spheroidization (PS), tag nrho lawv tuaj yeem siv los npaj kheej kheej lossis nyob ze. - spherical hlau hmoov
